Abstract (en)
[origin: WO2012062789A1] The invention relates to a method for measuring a current or voltage output quantity of a switched-mode power supply circuit (H), referred to as a chopper circuit, of period T and of cyclic ratio a, belonging to the interval ]0; 1[, such that, at each period, the supply current is non-zero during an "ON" phase of duration aT, and zero during an "OFF" phase of duration (1-a)T. The measurement method includes the following steps: measuring the value Gon of an image of the output quantity during an "ON" phase; measuring the value Goff of an image of the output quantity during an "OFF" phase; calculating the difference ?G = Gon - Goff,; and using the difference ?G for evaluating the output quantity.
